Matt Damon stars in Stella Artois and Water.org's ad airing during the massive football spectacular encouraging Americans to "Make Their Super Bowl Party Matter" by stocking up on the Belgian pilsner.

From now until April 15, every purchase of a Stella Artois 12-pack will help Water.org, which Damon co-founded in 2015, in providing a year of clean water to someone in the developing world. The same goes for ordering Stella Artois at bars. Every purchase of a limited-edition Stella Artois Chalice will offer five years of clean water for one person.

Between shots of running water, Damon shares, "Millions of people in the developing world walk up to six hours every day for water. This Chalice can change that. If just one percent of you watching this buys one, we can give clean water to one million people for five years."

‘Tonight’: Jimmy Fallon and Lin-Manuel Miranda Sing Holiday Parodies

Lin-Manuel Miranda and Jimmy Fallon sing a medley of popular songs from 2018, like Migos' "Stir Fry," Ariana Grande's "No Tears Left to Cry" and Cardi B's "I Like It," and change the lyrics to make them about the holiday season.

Damon hosted a promotional event for Stella Artois and Water.org's initiative in New York City, telling attendees why this project is so important to him and easy to take part in.

The "Downsizing" star recalled meeting a teenage girl on a trip to Zambia in 2006 who had dreams of becoming a nurse and said "reminded me of Ben Affleck and me when we were that age and we were going to move to New York and we were going to be actors." Damon said it was this interaction that made him realize a lack of clean water "robs people of any kind of hope" and their "true potential."
